You cannot choose where you were born, but you can choose where you live. Different places sends different messages and attracts different people. In this section we are interested to see regional effect on women’s income in the US. The main question here is: in which locations are women better or worse off?
First, we want to look at women’s income boxplots in all 4 regions to better understand women’s income distribution.
The boxplots of women’s income show that despite that all distributions are highly skewed to the right, the Northeast Region has the highest women’s income level of all 4 regions, followed by the West; Midwest has the lowest women’s income level, whereas South is only slightly better off than that. Then we will break down to state level to investigate further on women’s income level.
Income levels can be affected by many things. Cost of living is one of them. For example, In New York, everthing cost a little more than many other parts of the US, so people will only thrive by earning more money. Therefore, in order to remove the effect of cost of living that differs in different states, we calculate the percentage of median of each woman’s income by state and draw boxplot according to that.
